WILL NOT START on 2009 Dodge Challenger R/T

I GARAGE MY CAR ALL WINTER; I START IT EVERY FEW WEEKS - IT WAS STARTING FINE; THEN SECOND WEEK IN FEB WHEN I TRIED IT I GOT THE ETC WARNING LIGHT CAME ON AND STAYED ON AND THE CAR WILL NOT START; IT WAS STARTING FINE I DON'T GET IT; I LIVE IN LOCKPORT NY; ANY IDEAS? DEALER TOLD ME TO DISCONNECT THE BATTERY FOR A FEW DAYS AND RECONNECT AND TRY TO START AND I DID THIS BUT IT DID NOT WORK; STILL WILL NOT START; ELECTRONIC THROTTLE WARNING LIGHT IS ON- CAR TURNS OVER, JUST WON'T FIRE UP-ANY IDEAS/HELP? THANKS IN ADVANCE.

I think the throttle is stuck from moisture condensation causing ice or corrosion. You may need to tow the car to a Chrysler specialist if you can't get it started in the meantime.
FYI: Disconnecting the battery is no good, it's ignorant advice. Disconnecting the battery won't fix anything.
If you want to find a specialist, here's a directory link for you:

thanks so much for the answer, dealer does seem stumped; I don't get on line too often so I just got your answer and he goes on less than me. Anyway of course he has it all snugged up in the corner in the garage so he is having kittens about being able to get it on a trailer, does not want 16 year old kid doing it etc,...we still should have chrysler roadside assistance warranty - I suggested we take every thing out of the garage (30x40) and put it in neutral and GENTLY push on the bumper ONLY to try and get it in position. if you have any thoughts on that I would love to know them. He is just sick about the whole thing.

If the hubby is having kittens over a 16 yr old touching the "baby", then he needs to figure it out himself. I agree it isn't a pleasant thought, but you have a nearly 40k car just vegetating in a gagrage.....my hubby felt the same about his Mustang GT, he got over it. And I speak from personal understanding as my baby is a 2009 Hemi-Orange Challenger R/T. If my car refused to start today, by tomorrow it would be at a dealer being examined. End of story. Too valuable to just sit and wait to be figured out.

HI,
This happened to me in my 2013 dodge challenger. My vehicle stalled in the middle of busy traffic. I had less than 20 thousand miles on it. The problem turned out to be the Engine Control Module (ECM) It just went out. They repaired it and it went out again in 2 days. They eventually had to replace it. The ECM failed to communicate with the engine. Hope this helps.
